Most major health insurance carriers in the U.S. now have formal policies covering FTM top surgery (bilateral mastectomy with chest reconstruction) when it’s deemed medically necessary for the treatment of gender dysphoria. That said, coverage depends heavily on your specific plan, your state’s laws, and whether you meet your insurer’s documentation requirements. Here’s what to know before you start the process.
Which Insurers Cover Top Surgery
The largest national carriers, including Aetna, Blue Cross Blue Shield, Cigna, and UnitedHealthcare, all have clinical policy bulletins that include coverage for gender-affirming chest surgery. These policies treat top surgery as medically necessary rather than cosmetic, which is the key distinction that determines whether your plan pays for it. However, “the company covers it” and “your specific plan covers it” are two different things. Employer-sponsored plans can opt out of certain benefits, and some older or grandfathered plans still carry explicit transgender exclusions.
The first step is always to check your plan’s Summary of Benefits and Coverage or call the number on your insurance card. Ask specifically whether your plan covers gender-affirming surgical procedures and whether there is a transgender exclusion. Get the answer in writing if you can.
State Laws That Require Coverage
Twenty-four states plus Washington, D.C. have laws prohibiting transgender exclusions in health insurance. If you live in one of these states and have a state-regulated plan (most individual and small-group plans sold on the marketplace qualify), your insurer cannot categorically deny coverage for gender-affirming care.
Those states are: California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Hampshire, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and Wisconsin.
One important caveat: self-funded employer plans (common at large companies) are regulated under federal law, not state law. That means even if you live in one of these states, your employer’s self-funded plan may not be bound by the state mandate. You can usually find out whether your plan is self-funded or fully insured by checking your plan documents or asking your HR department.
What Insurers Require for Approval
Even when your plan covers top surgery, you’ll need to meet a set of medical necessity criteria before the insurer approves the procedure. Requirements vary by carrier, but Blue Cross Blue Shield’s policy is a good example of what most major insurers expect. Their criteria require all of the following:
- Age: You must be 18 or older.
- Mental health referral: At least one letter from a mental health professional who holds a master’s degree or equivalent in a clinical behavioral science field.
- Informed consent: You must demonstrate that you understand the effects of surgery on reproduction and that your reproductive options have been discussed.
- Stable medical conditions: Any significant health concerns like high blood pressure or diabetes need to be well controlled.
- Capacity to consent: Documentation that you can make a fully informed decision about treatment.
The referral letter itself has specific content requirements based on the World Professional Association for Transgender Health (WPATH) Standards of Care, Version 8. It needs to cover your psychosocial assessment, the duration of your relationship with the mental health professional, other treatments you’ve tried (such as therapy or hormone therapy), and a clinical rationale for why surgery is appropriate. The letter should also state that the provider is available for coordination of care with your surgical team.
Is Testosterone Required First?
This is one of the most common questions, and the answer is: it depends on the insurer and the surgeon. Some insurance policies still require a period of hormone therapy before approving chest surgery, while others do not. From a medical standpoint, surgeons often recommend waiting 6 to 12 months after starting testosterone before having top surgery. This allows the muscles and soft tissues of the chest wall to settle into their new pattern, which can improve surgical outcomes. But testosterone is not universally required, and some people who don’t plan to take hormones still qualify for coverage.
Medicare and Medicaid Coverage
Medicare has no national coverage determination for gender-affirming surgery. Since 2016, the Centers for Medicare and Medicaid Services has left these decisions to local Medicare Administrative Contractors, who evaluate claims on a case-by-case basis. This means coverage is possible but not guaranteed, and your experience will depend on which regional contractor processes your claim.
Medicaid coverage varies dramatically by state. States with transgender nondiscrimination protections generally cover gender-affirming surgeries through Medicaid, but the approval process can be slower and more documentation-heavy than private insurance. Some states cover hormones but not surgery, or cover surgery only for adults. If you’re on Medicaid, contact your state’s Medicaid office directly to ask about covered gender-affirming procedures.
What You’ll Pay Out of Pocket
Even with insurance, top surgery isn’t free. A study published in The Journal of Law, Medicine & Ethics analyzed commercially insured transgender patients and found that the average out-of-pocket cost for mastectomy (the primary procedure in FTM top surgery) was $2,177 in 2019 dollars. That represented about 15% of the total procedure cost. For context, the out-of-pocket share for other gender-affirming procedures like mammoplasty was lower, around 6.6% of the total cost.
Your actual costs will depend on your plan’s deductible, coinsurance rate, and out-of-pocket maximum. If you haven’t met your deductible yet for the year, you could owe significantly more upfront. Many people strategically time their surgery for later in the year after other medical expenses have already chipped away at the deductible, or they schedule consultations and pre-surgical visits early in the year to start accumulating costs toward it.
How to Navigate the Prior Authorization Process
Most insurers require prior authorization before they’ll pay for top surgery. This means your surgeon’s office submits a request along with your mental health letter, medical records, and any other required documentation. The insurer then reviews everything and issues an approval or denial, typically within a few weeks.
If you’re denied, you have the right to appeal. Denials often come down to missing documentation rather than a blanket refusal. Common reasons include an incomplete referral letter, a mental health provider whose credentials don’t meet the insurer’s requirements, or a plan that still has a transgender exclusion the insurer hasn’t updated. For exclusion-based denials in states with nondiscrimination protections, filing a complaint with your state’s department of insurance can be effective.
Some practical steps that improve your chances of approval: confirm your surgeon is in-network before scheduling anything, ask your surgeon’s office if they have experience billing for gender-affirming procedures with your specific insurer, and request a copy of your insurer’s clinical policy bulletin so you know exactly which boxes need to be checked. Having your mental health provider write the letter with the insurer’s specific criteria in hand, rather than a generic letter, makes a significant difference in first-pass approval rates.
